Is there anybody alive who knows how to get the last grains of salt out of a Morton Salt box?

If so, what’s the trick (short of cutting into the box)?

I hear them rattling around in there, but no matter how I tip it, I can’t seem to get them to tumble across the pour spout and fall out.

It’s not that I can’t spare those few grains. I’m sure they’ll find their way back into the earth where they belong. It’s just the idea of the thing.
